Kicking and screaming into reality

I recently purchased the script, and I want to make my new tube style site compatible with the realities of current surfers.
On one site that we own, the resolutions that the surfers are using are nowhere near what vshare has built in.
Out of 1.2 million visitors last month, 43% are at 1024x768, 6% are at 800x600 (so they're too cheap to buy a real computer) and the rest are 1280+
This, obviously, means that over 50% of my surfers are running a resolution of 1280 wide or greater.
I find that a site built at 780 or so wide is NFG. (barely half the screen)
It seems to be easy enough to deal with the tables, ads, and whatnot, but what I'm having a problem with, is finding out where to get the script to make the thumbs a decent size.
120x67 just does not cut the mustard. (looks like a thumbnail of a thumbnail :mrgreen: )
I need to be able to set the size of the thumbs, and also the quality. (and, no, I don't mean the apparent size as seen in the height/width tags, but the real size)
Also, setting the size and quality of the video made would be nice.
I know it's in there somewhere, but I just can't find it.
